"Super Classroom", "Handbook of Important and Difficult Points" and "3.1 Test". At the beginning of mathematics, we should start with the basic problems, take the exercises in the textbook as the standard, practice repeatedly and lay a good foundation. In order to further cooperate with teachers and students in teaching or reviewing for preparation, the ninth grade mathematics synchronous exercise book includes Super Classroom, Handbook of Important and Difficult Points and Three Point One Test. Workbooks are auxiliary, mainly focusing on listening to lectures in class, reviewing in time after class, and accepting new knowledge. The cultivation of mathematical ability is mainly in class, so we should pay attention to learning efficiency and seek correct learning methods in class.
